The problem is that Apple's Mac Pro uses FOUR PCIe 2.0 lanes, not TWO lanes as on existing PCIe SSDs. This gives the Mac Pro a maximum of 2GB/s bandwidth, twice what existing PCIe SSDs have. Since Apple is the only one doing this, and since the Mac Pro is a low volume seller, Samsung is simply not interested in creating a low volume product. If other PC Makers also would use FOUR PCIE 2.0 lanes for their SSDS, then Samsung may be interested. Otherwise, not.

OWC is great in supporting Apple's customers. And they are able to do low volume custom products.Reply

x4 SSDs aren't unheard of. Most of OCZ's PCIe lineup seems to be x4. Kingston demoed an x4 board at CES. The M.2 products we've seen so far seem to be of both varieties, but M.2 isn't even fully adopted yet. The SF3700 (what these upgrades are going to be using) allows four lanes.Reply

What I would love is a DUAL DRIVE PCIe SSD for the new Mac Pro that you can arrange as a RAID-0. The reason is that despite the speed of the existing single-drive 4-lane PCIe SSDs from Apple, it wastes the even faster 2GBs bandwidth of the Mac Pro's SSD slot.Reply

This might be a stupid question, but is it even possible to use multiple SSD's in the new Mac Pro and set them up in a RAID set up? Or would you have to use an external solution via Thunderbolt/USB?Reply

Apple problably made an agreement to be the only one aloud to sell the product so they can be first. Also Apple could ohf just said will buy every pci sdd in this form factor that you produce so no one else can have it. They get it for cheap, even if premium price till makes Apple look good.Reply

OWN Trivia factoid: They're based out of this little shit town in Illinois called Woodstock. There's really no reason anyone should ever go there unless you own a farm. The building is almost entirely powered by a wind mill they set up on their property. Reply

I am now VERY skeptical of the OWC SSD's. I got an MBA w/ 126 GB SSD in 2010. I replaced the drive w/ OWC's 240GB one. Since then two SSD's went bad and I am now on the third one. Is this usual or acceptable? I would like to know... On top of that, the OWC has a policy that requires you to send the bad unit to them first before getting a warranty replacement! What kind of logic is that? So, am I supposed to stop what I am doing, get the drive out, send it to them, wait until they verify that the drive is indeed bad, and wait more until they ship the replacement? Do they think I use a Mac for a hobby? I want to know the others' experience with the OWC drives' reliability. What's AnadTech's opinion on this?Reply

Good question. I've been considering buying and the upgrading a rMBP with an OWC drive to get the extra external but this and the power use are both pretty key. I'd check OWC forums or elsewhere for the reliability of their drives. I know that with a first gen SF Corsair drive, I had to send it back before they sent me a new one. Rediculous. Reply
